1. Was NORAD aware of the four hijacked planes veering off course even
before being reported by the FAA? If not, please explain why NORAD
which monitors 7000 flights a day, was unable to track the four aberrant
flights.

Linda Slobodian writes in “Norad on Heightened Alert: Role of air defence agency
rapidly transformed in wake of Sept. 11 terrorist attacks”

“Where was Norad, the multimillion-dollar, 24-hour eyes and ears of North
American skies, when the hijacked planes embarked on their sinister missions?

Ironically, Norad was doing its job: peering 300 kilometres out into the Air Defence
Identification Zone encircling North America. Its task: to help assess, within two
minutes, if each of the 7,000 incoming aircraft every day is friend or foe….

When the second plane hit the other World Trade Center tower, Norad swiftly shifted
its attention to help prevent possible further attacks.
